Locating C States and C1E Settings in the BIOS
System Administration (18%)
* Configure BIOS, Storage, virtual media, networking, user access, lockdown mode, and group management Understanding C States and C1E
* C States: CPU power management features that allow the processor to enter low-power idle states to conserve energy when idle.
* C1E: Enhanced C1 state; a deeper power-saving mode that reduces CPU voltage and frequency.
Impact on Performance
* While these features save power, they can introduce latency due to the time required for the CPU to transition between power states.
* Disabling C States and C1E can improve performance and reduce latency, which is crucial for latency- sensitive applications.
Locating the Settings in BIOS
* Enter BIOS Setup
* During server startup, pressF2to enter the System Setup (BIOS) utility.
* Navigate to System Profile Settings
* In the BIOS menu, selectSystem BIOS.
* Then selectSystem Profile Settings.
* Adjust C States and C1E Settings
* WithinSystem Profile Settings, you can:
* Set theSystem ProfiletoPerformanceto automatically disable power-saving features.
* Manually disableC StatesandC1EunderCPU Power Managementif customization is needed.
Explanation of Options
